Lollipops:

This is a face to face based sales fundraiser that's very easy to sell.

Lollipops are so cheap and popular that your sales team will find it so simple to go around and sell your stock out quickly.

Just ensure you have prepared your sales team properly!

I'd highly recommend you read Jack Atwell's book "Let's Raise Money"
to get some of his invaluable experience in fundraising sales. He
provides some excellent advice on getting the most from your sales team!
